nec'ts, through bevel-gears 32 33, with a cen- 4 tral vertical shaft ,34;

a 35b '35 35d are Jfour vertical cornershafts, reach consisting of a lower section 36 and an upper section 37, having a pinion 38. The several pinions mesh with the teeth of gears 39von the peripheries of four .drawingdrums 40n 40b 405 40 ,which are hung on dead orv nonrotating studs A41, Fig. 9, which depend from the four'corners of the upper f frame-plate 42. The lower shaft-sections 36 constantly rotate, andtheir motion is communicated to the alined upper lsections 37 through four clutches 43, having upper seclower sections 45, splined to the shaft-sections 36,-Fig. 7. 'The clutch members 45 are operated by levers 46, links 47, and hand-levers 48 and are weighted, so that gravit;T .carries them out of engagement With the upper members 44 when` there is no strain on'the clutehes.- vThe clutch members are provided vus tions 44, secured to the shaft-sections 37, and

with saw-teeth, as `shc wnh`a vin -vertical hen the drivinfg-faces and inclined backs.

thewire causes a resistance to the rogagement with the upper members 44, andthe lower -sl 1ar`tsc .'ctionsv will drive the upper the 'centralV shaft 34 constant y drives four llarge ears 50 on the shafts 35a 35b 3,5c 35d, -.and t ese' gears drive the last'said shafts through single-acting roller friction-clutches IOO 51 when th',- said shafts ane not rotated at a i faster spesi by the gearing placed lower down on ne shaft and presently to be described.

-In addition to the lowest speed imparted by the pinion 49 and gears 50 each of the shafts 35h35c 35d has two higher 'speedsband the shaft 35a has one higher speed. The'central shaft 34 has a c ne of four gears 52 53 54 55, Fig. 5,of graduated size iixed to it and engaging `complemental gears 56 57 58 59 on the several lower shaft-sections 36, thel lastsaid gears being connected'to and disconnected from the said shaft-sections by friction-clutches 60, (shown in `detail in Fig. 7,)

y the movable members of .which are operated by arms 61, Fi 1, and rock-shafts 62, which are oscillatedy handles 63. Each of the shafts has a gear 59, 'mesh` with the largest central gear 55, so thatul. of the cornershafts'have the same highest and lowest speeds. The 'handles 63 are removably mounted on the squared ends of the rocking engaged at the same time, to the damagev shafts 62, and their hubs are assed through .holes64'in movable locldng-p ates 65, Fig. 1. Each locking-plate, except the one correspending to shaft 35a, has two of said holes and is recessedabove and below the holes to permit the plate to slide and bring one or the other of the two holes into central relation with the upper and lower shafts 6,2. The holes are nearer together in the plate than the distance between the upper and lower shafts, so that the handles 63 can only be laced on one shaft of the pair at a time. lhis revents the upper and lower frictionclutc es on the same shaft from both beof the machine.

It is evident that should any of the shafts 35a, &c., be rotated at its slowest speed through pinion 49 and gear 50 it can be raised to a higher s ,eed by throwing in one of the clutches 60. lllhe gear 50 will continue tprotate, but will be released from the shaftsection 36 by the automatic action of the .clutch 51, Fig, `4, which ermits said shaftsection to rotate at a hig er speed than the gear.

As indicated, the drums 4 0a 40b 40c 40d are inverted andtapered downwardly and unobstructed underneath. The coils of wire when finished, are therefore removed from the drum by ,a downward movement. The .gears 39 project beyond the largest diameter of the wire-receiving ortion of each drum, so as to permit a sma l pinion 38, Fig. 9, to be employed and the size of the gearing underneath the frame-plate or table 66 to be reduced. The wire 67 passes to each drum through a die 68, Figs. 12 and 13, mounted in a holder 69, secured to the frame-plate 42.

Each drum 40a, &c., has vertical slots 70 formed in it, through which normally project a series of coil-supporting hooked arms 71 71,

-cured a chain 86,.

l pivoted at 72 72 to a hub or spider 73, Figs.

9 and 10, located partly within the hollow stud 41. Said spider is formed with a hollow stem or sleeve 74, having a collar 75 at its upper end, between which and a partition in the stud 41 is interposed a spring 76. Between the upper end of said spring and the collar 75 is an antifriction-bearing 77, which permits the spider 73 to rotate freely without rotating the spring. When the arms 71 are radially extended, as indicated in Fig. 9, they are so held by links 78, ivoted to said arms and to a central bloc i 7.9 upon the lower end of a rod 80. In other words, said block 79 when in the position shown in Fig. 9 constitutes ositive arm-locking means, which will holdp the arms 71 radially extended throu h the medium of the links 78, and said bloc 79 is movable, as indicated by comparing Figs. 9 and 10, in a direction transverse of the direction of thrust of the links from the arms toward the block, so that when said block is moved from the position shown in Fig. 10 to the position shown by full lines in Fig. 9 the arms will be held in projected positlon. The several rods 8O re- .celve movement Jfrom levers 81, having depending handles 82, said levers rojecting through 'slots 83 in casings 84, which inclose the springs and adjacent parts. The stress of the springs 76 is such as to increase proportionately with the weight ofthe coils, sathat the descent of each coi ,is prop ortionel'to the accretion at its upper end. Normally the arms are yieldingly su orted. adjacent to the initial drawing-su A'ace of the drun1,.so that the base of the coil moves downwardly as its height and weight increase. A naising of the rod-80 through the sleeve 74 by manipulation of the handle 82 allows the arms '71 to collapse, as shown in Fig. 10, and

permits the coil of wire to be removed from the drum. t

Each' drum 1s formed with an inclined groove 85, Fig. 12, in one end of which is sechain is secured a gripper 87, adapted to engage the end of the wire projecting through the die. IAs the drumrotates the chain 86 wraps itself within the groove 85 and'draws the end ofthe wire toward the base of the drum. The end of the wire reaches the periphery of the drumn as the .chain becomes completely sunk within its groove, and the wire then winds upon the drum, the operation of drawing out or starting the wire being therefore continuous with the operation of winding the wire upon the drum. The inclination of the groove 85Lprevents the wire from dropping into the groove as it winds upon thedrum.` When the chain 86 is not in use, it may be held within its groove by a pin 88, Fig. 14, removably mounted in a` hole 89,'Fig. 14, and engaging the gripper 87. The chains 86 on the drums are for use IIO To the free end oi" said "ffpfed" o f 'den 9T o the-head; 'oS'ai-d-prop has; *al handle] 'Seeed' -grooveyand 'attaches the gripper .87h11 they l end :ofi saidchaiififto, I'the 'pointed endy of fthe A i hema assedervim ".tli ,first drum, econ'd passed around a 1 ld so on eldin'gly racted into operative.

two gearings for driving one drum of the series either at a low speed and at a higher (speed, three gearings for driving the ynext rum ofthe series at a low speed and at two higher speeds, and one-way-acting clutches to connect the low-speed gearings to the drums--I am enabled to operate either drum independently of the others or to operate any two or more as units or members of a series, which may include all the drums of the series or any lesser number.
